Die Firma produziert eine recht spezielle Software, Daten-import/-export, das läuft vsl. über ne GUI.
Wie testet man Java-GUIs? Bei normalen Windows-Apps kann man da mit AutoIt ran ("You can expect to move, hide, show, resize, activate, close and pretty much do what you want with windows. Windows can be referenced by title, text on the window, size, position, class and even internal Win32 API handles. Directly get information on and interact with edit boxes, check boxes, list boxes, combos, buttons, status bars without the risk of keystrokes getting lost. Even work with controls in windows that aren’t active!")
